For example, the samples show the structure of the 13 manifest file and the use of activities, services, resources, 14 intents, content providers, and permissions. They also show how to add 15 specialized capabilities to your apps, such as Bluetooth and Contacts 16 integration, multiple screens support, Live Wallpaper, and more. </p> 17 18 <p>The SDK provides the samples both as source code and as browseable HTML, as 19 described in the sections below. All of the samples included in the SDK are 20 licensed under the <a href="http://www.apache.org/licenses/LICENSE-2.0">Apache 21 2.0 license</a>, so feel free to use any of the code in your own applications as 22 needed!</p> 23 24 <h3 id="downloading">Downloading the Sample Code</h3> 25 26 <p>The SDK sample code is available to you as a set of downloadable SDK 27 components, each of which contains the samples for a specific Android platform 28 version. Once you have installed the SDK, you can download one or more samples 29 component(s) into your SDK environment using the Android SDK and AVD Manager 30 tool, which is pre-installed in the SDK. </p> 31 32 <p>To download the samples, launch the Android SDK and AVD Manager tool and 33 select one of the samples components from the <strong>Available 34 Packages</strong> panel, for example "Samples for SDK API 7". Select 35 <strong>Install Selected</strong>, verify and accept the download, then select 36 <strong>Install Accepted</strong> to download the component into your SDK. If 37 you aren't familiar with the Android SDK and AVD Manager and how to launch or 38 use it, please read the <a href="{@docRoot}sdk/adding-components.html">Adding 39 SDK Components</a> document. </p> 40 41 <p>When the download is complete, you can find the samples sources on your 42 computer in this location:</p> 43 44 <p style="margin-left:2em"> 45 <code><em><sdk></em>/samples/android-<<em>level</em>>/</code> 46 </p> 47 48 <p>You can easily create new Android projects with the downloaded samples, modify them 49 if you'd like, and then run them on an emulator or device. </p> 50 51 <p>For example, if you are developing in Eclipse with the ADT Plugin, you can 52 create a project for the "API Demos" sample app by starting a new Android 53 Project, selecting "Create project from existing source", and then browsing to 54 the <code><em><sdk></em>/samples/android-<<em>level</em>>/ApiDemos</code> 55 directory (the <code>samples</code> directory for the platform version you are 56 using).</p> 57 58 <p>If you are not working in Eclipse, you can create a project for the API Demos 59 sample using the <code>android</code> tool, by executing this command:</p> 60 61 <pre class="no-pretty-print"> 62 android update project -s -n API Demos -t <em><target_ID></em> -p <<em>path</em>></em>samples/android-<<em>level</em>>/ApiDemos/ 63 </pre> 64 65 <h3 id="browsing">Browsing the Sample Code</h3> 66 67 <p>For your convenience, the SDK provides browseable source code for the latest 68 versions of the samples. You can use your browser to navigate through the 69 structure of each sample and look at the source code in each of its files. </p> 70 71 <p>To browse the samples, go to the <a 72 href="{@docRoot}resources/samples/index.html">List of Sample Apps</a> first. 73 From there you can read a short summary of each sample application and what 74 types of concepts, features, or APIs it includes. Then, use the links provided 75 to move through the directories and files of each sample. The browseable source 76 is generated from the same source code that is downloadable through the Android 77 SDK and AVD Manager, as described above. </p> 78 79 <p>The browseable samples files are available online, at the Android Developers 80 site only and are not included in the downloadable offline documentation. 81 Note that, although samples for several platform versions are available for 82 download, only the samples for the latest platform version are browseable online. 83 </p> 84 85 86 <h3 id="more">More Sample Code</h3> 87 88 <p>If you are looking for more sample code, check out 89 <a href="http://code.google.com/p/apps-for-android/">apps-for-android</a>, a 90 collection of open source applications that demonstrate various Android APIs.</p> 91 92 93
